Specification of Letters Patent.

Patentedduly 19113.

To all whom it may concern Be it known that we, Wmnmsr W. Wan son andJenn Gr. Crimson, citizens of the United States, residing at the cit yoiJamestown, in the county of Chautauqua and State or" New York, haveinvented certain new and useful Improvements in Suspensions forFiling-Drawers, of which the following, taken in connection with theaccompanying drawings, is a specification.

The invention relates to supports for drawers of filing cases, and theobject of the improvement is to provide a simple and convenient form oftelescoping suspension means for each side of the drawer, whereby thedrawers are held in a horizontal position within the cabinet or filingcases or in front of the same when withdrawn, and their outward movementis limited so that while the drawer is entirely withdrawn from the case,yet there is no danger of spilling or dumping its contents, since it isfirmly supported by said suspension means; and the invention consists inthe arrangement and combination of the parts as described in thisspecification and shown in the-accompanying drawings and pointed out inthe claims.

In the drawings, Figure 1 is an elevation of one of the suspensionslides in the extended form, showing a portion of the case in solid lineand the drawer in dotted outline; and Fig. 2 is elevation of the slidein the closed position. Fig. 3 is a crosswise sectional View of thedrawer and portions of the caseat each side and elevationsof the closedsuspension slides at each side from their front end. Fig. dis a detailperspective View of portions of the case or frame of the cabinet and theguide strip or that part of the telescoping slide which is attached tothe case; andl igu. 5 is a perspective view of the loose extension slideor central part of the telescoping slides; and Fig. 6 is a perspectiveview of the guide strip or sliding memher which is attached to thedrawer; and

drawer from the case.

Like numerals of reference refer to corresponding parts in the severalviews.

The numeral 19 designates a portion of a cabinet or filing case providedwith drawers 1].. The guide strips 12 are attached to "the frame 1-0each side the drawer ill. and are made of sheet meta in semi-tubular oreha11- n-el shaped, that is, the upper and lower edges are turned so asto embrace the channel shaped central or extension supporting member 18therein and a portion guide strip 2.9. The member 13 has the turnedlengthwise flanges 14 and 15. [he flange 14 is cut away at 16 for apurpose hereinafter set forth. Near the rear end of the slide 13 theflange 14 has a lengthwise slot 17. to receive the spring dog 18, whichdog is pivot-ally mounted on guide 12 so that the end of said dog rideson flange lt until the drawer is withdrawn its full length, when the dog18 enters the slot 17 and acts as a stop to limit the further withdrawalof the The dog 18 is preferably pivotally attached to a lug i0 struckfrom the guide 12 and extending upward therefrom. A spring 39 engagesaround the pin for the dog 18 and attaches one end of the lug d0 and theother end extends out over the guides 12, thereby pressing dog 18 downupon the flange 14 v as the drawer slides back and forth. The rear endof the member 18 is turned upon itself, as shown at 1.9 in 9, therebyforming a loop within which the two wheels or rollers 20 are rev olublymounted so that they extend above and below the upper and lower edges ofthe member 13. The central portion 21 of the sheet metal of the loop 20is cut away on one side to form the some into a flat hook, as shown inFigs. 8 and 9, to clasp around the butter block 2 and hold the samefirmly in position and attached to the end of the member 13 to form abutter for said rear end to strike against the turned up end 23 of guide12. A second butler block 24 is inclosed within flanges 1i and 15 attheir rear ends and rests against the loop 19. The front end of themember 13 is provided with a buffer block 25 which is inolosed within astruck out loop or blister 26, being preterably wedge-shaped so to holdfirmly within said blister. The end of the member 13 is turned inward at27 and a wheel or roller 28 is revolubly mounted therein. The thirdmember of each of the telescoping slides or suspension device is a guidemember 29 which is attached to the side of the drawer l1, and has itsupper edge turned in a horizontal flange 30, which has a return bend 31so as to form an upwardly extending inclined guide flange 32 lengthwiseof the guide strip 29, the bends 30 and 32 forming a V-shaped flange.The flange 32 is cut away at 33, a small portion 34: at the rear endbeing left to guide toward the roller or wheel 35 which is revolublymounted on the rear end of the guide strip 29. The wheel 35 preferablyhas a rounded edge to diminish the frictional contact. A projecting lug36 is attached beneath the flange 30 midway of the length of the strip29 to engage within the flange 15 and hold the parts in line and also toform a stop when the drawer is withdrawn from the case. A roller orwheel 37 is revolubly mounted on the case in front of the lower edge ofthe guide strip 12 for the extension strip 13 to roll upon, as shown inFigs. 1 and 8.

The suspension is assembled in the following manner: The guide strip 12is attached to the casing as hereinbefore described and the guide strip29 is attached to the drawer side. The loose or extension slide 13 isfirst inserted in the guide 12, the rollers 20 making the strippractically frictionless in so far as the rear end is concerned. Theroller 37 receives the front end of the extension strip 13 so that saidextension strip rolls freely backward and forward within the guide strip12. The spring dog 18 is presscdupward by the insertion of the guidestrip 13 and rides on the upper flange 14 forming a spring stop againstthe withdrawal of the guide strip 13, the rear end of the dog 1.8entering the slot 17 against the bufl'er 24, as shown in Fig. 1. Thedrawer '11 with the guide strips 29 attacliedthereto is then inserted byentering wheels 35 within the open ends 16 of the flanges 14, the wheels35 find a track or hearing on the under side of flanges 14, and theflanges E30 enter within the flanges 14. holding the parts firmly inline, yet permitting them to slide backward and toruau'd freely. Therollers 28 bear against the undcrsideof the flanges 30 as the partstravel backward and. forward and the stops 36 strike against thebull'ers 25 when the suspension is in the withdrawal position, as shownin Fig. l.

l t is obvious that the parts may roll backward and forward freely, andthat the drawer will be suspended or held firmly in the horizontalextended position, as shown in Fig. 1 before the case it) so that thecontents of the drawer are all easy of access.
